Programming a thermistor with Arduino

Other Hardware General Electronics
1

Hi,

I want to measure the temperature with an Arduino Uno using this NTC thermistor: http://skpang.co.uk/catalog/temperature-sensor-waterproof-ds18b20-p-1059.html
I've had a look at the datasheet (there's a link to it on the web page) but I can't figure out what the code for figuring out the temperature should look like. Any ideas?
Also, I have a circuit with a program that will let me control some servos with potentiometers. I want to hook the thermistor up to that, but I'm afraid it will pull too much current from the other parts of the circuit. Do you think that will be an issue?

Thanks a lot!

It's not an NTC Thermistor.

The DS18B20 is a Onewire-digital temperature sensor.

NTC is an temperature-dependant resistor you read with one of the analog pins.

Don't mix things up, you will only make it harder for your self this way.
